The ATTO bridge would be monitored via cluster and most likely it should be through the in-band monitoring.
Please check "storage bridge show" to see the monitored bridges.
In-band basically accesses the bridge via the FC connection where disks are accessed through.
You can run the command "storage bridge run-cli -name <bridge name> -command" followed by the command you need to execute
To get a list of supported command, run "storage bridge run-cli -command" and press "tab" key
Eg:
::> storage bridge run-cli -name ATTO_2000001086aXXXXX -command info
